The commercial astragon lens i received on the 5x7 handheld camera was very hazy on the front element.
I dismantled the cells and placed in it soapy scolding hot water and gave it a gentle run over the lenses.
By the time it dried the mottled appearance is still etched on the glass but at least it's a lot clearer on the ground glass now.
What techniques do you guys use to clean a mucky lens element?
